Suction body providing electric energy and cleaner having the same

Abstract

A suction body for a cleaner is provided that can generate electric energy by itself using air drawn in by the cleaner. A suction body includes an ultraviolet sterilizer that radiates ultraviolet rays toward a surface to be cleaned and sterilizes the surface to be cleaned, a lighting device that emits light, a displaying device that displays a cleaning state, a fan that rotates by drawn-in air, and a generator that converts rotary energy of the fan into electric energy so as to supply the electric energy to the ultraviolet sterilizer, the lighting device, and the displaying device.
